ANAEROBIC DIGESTION
What is Ireland’s Anaerobic Digestion Potential? » There is immense untapped potential in Ireland. » There is the potential to create €1.5 billion in direct investment through AD development along with significant environmental benefits. Within many European countries, AD and the production of biogas has been supported by policy for many years. AD in Ireland has yet to receive the attention and policy support needed to accelerate its development, leaving the country falling behind many of its EU counterparts. Studies, however, have shown that Ireland has the highest potential for biomethane production per capita within the EU135. With a strong agricultural sector that devotes 2/3 of land to agricultural use, comprised of 140,000 individual farms and accounting for 5.7% GDP, Ireland boasts comparative advantages in this sector136. This extensive biogas potential comes from various resources including, grass silage, slurry, food waste, sewage sludge, seaweed, and organic fractions of municipal solid waste (OFMSW)137. Co. Cork in particular holds the highest potential for AD feedstock in the country, boasting the largest number of dairy cows at 378,200 head138. A 2012 IrBEA study found the following economic benefits from the deployment of bioenergy infrastructure in Ireland139: » The creation of 3,600 new permanent jobs; » €1.5 billion in direct investment; » The generation of over 8,000 work years during construction and installation; » Securing family farm income through farm diversification; » A reduction in Ireland’s energy import bill by 7.5per cent; and
» The provision of a secure and competitive indigenous energy source for Irish homes and business. Additional potential benefits to developing Ireland’s AD and biomethane industry include: » Saving over 2.6m tonnes of CO2 emissions per annum140. » 35% to 48% reduction of Irish agricultural GHG emissions141. » Utilisation of 4.8m tonnes of animal slurry per annum142. » Decarbonisation of industry, domestic heat, and transport. » The transitioning of Ireland into a global circular economy leader. These latent economic and environmental benefits that could be activated from embedding this circular technology into the country’s energy system have been recognised by Cork’s business community through the Sustainable Cork Programme, Building Economic Resilience Report143. Capitalising on this green energy is critical to boosting our local and national green credentials and enhancing the regions attractiveness to FDI.
